Actually, lowering the voltage would lower the current draw too with a constant load. Of course a motor is anything but a linear load, and it does tend to draw more current at slower rpm. In any case, you're not going to break it, since the 9v train (...) (25 years ago, 23-Aug-99, to lugnet.trains)
